About this Simpsons episode:The Simpsons - Waverly Hills 9-0-2-1-D'oh is the 19th episode of season 20 and number 439 overall in the series.
In this episode, while desperately searching for a bathroom during her morning jog, Marge
discovers how low-rent Springfield Elementary School really is and
moves Bart and Lisa to Waverly Hills Elementary by having Homer rent an
apartment there so the city inspector of Waverly Hills (who cracks down
on out-of-towners who only register for a Waverly Hills address so they
can send their kids to that town's school) does not get suspicious.

Fox have released a promotional image for Sunday May 3′s premiere of “Waverly Hills 9-0-2-1-D’Oh”:
When Marge learns Springfield Elementary is the worst school in the state, she and Homer rent an apartment in the upscale Waverly Hills neighborhood so Bart and Lisa can attend a better school. When Lisa is ostracized by the popular girls at Waverly Hills, Bart uses his newly established bad boy image to impress the other students and increase Lisa’s popularity by telling everyone she is best friends with the pop star Alaska Nebraska (guest voice Ellen Page).
